Self-rated performance predicts objective performance over and above other-rated performance

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 3 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Evidence does not support the idea that self-rated performance predicts objective performance better than other-rated performance; in fact, literature frequently demonstrates that informant and peer ratings are more strongly correlated with objective outcomes due to self-assessment biases.

The analysis

The claim states that self-rated performance predicts objective performance over and above other-rated (informant/peer) performance. The provided papers (such as 1, 3, and 5) consistently show that other-rated performance (peers, caregivers) or objective assessments are often superior or more accurate predictors of actual performance, and that self-ratings suffer from biases like the Dunning-Kruger effect. None of the provided papers support the superiority of self-ratings over other-ratings. Therefore, the claim is refuted by the available evidence.
